in the face of danger its your natural impulse to care for others. I had a similar dream once: I was standing in an open area, and suddenly baby birds kept falling out of the sky, I tried to catch them, but soon there were falling so many at once you can catch only so much, soon I had my arms full with catched birds but they kept falling and crashing on the ground around me at all sides like rain. frustration about the inability to not be able to save all. then I awakened.
it shows you, that even if you do everything in your power and do everything right, life will still fuck you and the ones you love.
